Method for controlling function and electronic device thereof

Abstract

A method of controlling a function of an electronic device is provided. The method includes determining whether a human body of a user is in contact with the electronic device, and performing a corresponding function if the human body of the user is in contact with the electronic device. The determination of whether the human body of the user is in contact with the electronic device is based at least in part on whether an image pattern of the human body of the user, which is detected by the image sensor, a temperature pattern of the electronic device, which is detected by the temperature sensor, and a resistance pattern of the human body of the user, which is detected by the body conductivity sensor, respectively correspond to a reference image pattern, a reference temperature pattern, and a reference resistance pattern.
